i get stuck on step 4, how do i open the inventories of both of my companions at the same time?
edit: i just found out the glitch is patched.
The names at the tops of the inventory allow you to change which character's inventory you're looking at. You might have to scroll the panel to get the item images to refresh tho.
Yes, the patch notes indicate the glitch is fixed, but I was able to reproduce the glitch using the steps descibed on v0.5.0c, the latest public release.
